TL:DR - fuel pump (suspected) making large droning noise at a standstill, is this normal?
Long version...
Hi! My 2019 VRS TSI has always had a drone at a standstill, until now Ive been thinking it was some.sort of auxillary cooling system for the turbo or some such. Ive been getting more and more suspicious of the fuel pump until someone mentioned theirs on a facebook group today!
So when I got home and parked up, with my foot on the brake (DSG) I can hear this very inrusive droning mechnaical noise. Sounds like the aircon fans are bad or similar to bad tyres on a rough road. Its not 100% constant it kind of oscillates a bit. If I let the DSG engage and start to move it stops straight away, although I have noticed it at low speeds some times. I put the car in P, disabled start stop and got in the back of the car. I noticed straight away that the rear bench seat was vibrating. Putting my ear to it I can hear the noise much clearer. Today I have 80 miles ramge left so the tank is quite low.
I dont know anything about these fuel pumps, if they are submerged in the tank or whatever. This does seem an unusual noise. My previous MY16 didnt do it and neither have any of my other cars for the last 20 years!
The nearest dealer is now 45 miles away and I'd need to take time off to get it there, plus likely pay a diagnostic fee ao I'm hoping someone can ahed some light on this for me? I may be able to record it but might have trouble isolating the noise. I could perhaps get the bench seat out at the weekend if anyone has any tips?
So yeah, does anyone else have a really loud droning noise when stationary (mother in laws etc discounted)? Are the fuel pumps known to be noisy?? Any help gratefully received!!!
Car is a MY19 VRS Petrol 245 DSG (GPF) with 4k miles on it for reference!
